..DISCUSSION FROM RNOFWFVEF
SLIGHT CHANCES OF SHOWERS AND THUNDERSTORMS ACROSS MOHAVE COUNTY
EACH AFTERNOON CONTINUE THROUGH AT LEAST THURSDAY. WIDESPREAD
CHANCES OF WETTING RAIN ARE LOW DUE TO THE ISOLATED NATURE OF THE
THUNDERSTORMS; HOWEVER, WITH THUNDERSTORMS THAT FORM, EXPECT
WETTING RAIN AND FREQUENT LIGHTNING. OTHERWISE, THE REGION WILL
REMAIN DRY WITH AFTERNOON RELATIVE HUMIDITIES WEST OF INTERSTATE
15 IN THE UPPER-SINGLE-DIGITS TO LOW-TEENS. WIDESPREAD GUSTY
SOUTH-SOUTHWEST WINDS BETWEEN 25 AND 35 MPH WITH OCCASIONAL
INSTANCES APPROACHING 40 MPH EACH AFTERNOON THROUGH AT LEAST
THURSDAY.
..DISCUSSION FROM LAXFWFSGX
A LOW PRESSURE SYSTEM MOVING SOUTHWARD ALONG THE COAST INTO
CALIFORNIA WILL BRING STRONGER ONSHORE FLOW, SLOW COOLING, AND SLOW
DEEPENING OF THE MARINE LAYER INTO WEDNESDAY. LOWEST HUMIDITY FOR
THE AFTERNOON FOR THE DESERTS ONTO THE DESERT SLOPES OF THE MOUNTAINS
WILL FALL TO 15 TO 20 PERCENT WITH SOUTHWEST TO WEST WINDS
GUSTING TO 25 TO 35 MPH DURING THE AFTERNOON AND EVENING THROUGH
WEDNESDAY. SLOW WARMING AND WEAKENING WINDS FOR THURSDAY THROUGH
SATURDAY, THEN A FEW DEGREES COOLER FOR SUNDAY AND MONDAY.
..DISCUSSION FROM PHXFWFPSR
PERIODS OF SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THROUGH
WEDNESDAY ACROSS THE EASTERN DISTRICTS SUPPORTING A HEAVY
RAINFALL AND LOCALIZED FLOOD THREAT. MOISTURE LEVELS WILL REMAIN
ELEVATED EXCEPT FOR SOUTHEAST CALIFORNIA. EXPECT MINIMUM HUMIDITY
LEVELS TO STILL FALL INTO A 15-25% RANGE FOR THE WESTERN DISTRICTS
WHILE THE EASTERN DISTRICTS WILL ONLY DIP TO 35-50% THROUGH
